How is Chemistry Taught & What Topics are in Exams?

I'm going to be a Year 12 in September, so during the quarantine I did some revision, and tried to learn a bit of the Chemistry A-Level spec. I've noticed that the topics are split weirdly in exams for AS Level and A-Level. From what I understand, at the end of Year 12 you take the AS exams (to check your progress, ect.), and then in Year 13 you take the A-Level exams. Is that correct?

Are these topics correct?:

AS-LEVEL
Paper 1:
Physical:
3.1.1 Atomic structure
3.1.2 Amount of substance
3.1.3 Bonding
3.1.4 Energetics
(skip out 5)
3.1.6 Chemical equilibria, Le Chatelier’s principle and Kc
3.1.7 Oxidation, reduction and redox equations
+ Inorganic:
3.2.1 Periodicity
3.2.2 Group 2, the alkaline earth metals
3.2.3 Group 7(17), the halogens

Paper 2
Physical:
3.1.2 Amount of substance
3.1.3 Bonding
3.1.4 Energetics

+ Organic:
3.3.1 Introduction to organic chemistry
3.3.2 Alkanes
3.3.3 Halogenoalkanes
3.3.4 Alkenes
3.3.5 Alcohols
3.3.6 Organic analysis

A-LEVEL

+ All of Inorganic Topics

Paper 2:
Physical:
3.1.2 Amount of substance
3.1.3 Bonding
3.1.4 Energetics
3.1.5 Kinetics
3.1.6 Chemical equilibria, Le Chatelier’s principle and Kc
(Skip 7 & 8)
3.1.9 Rate equations (A-level only)
+ All of Organic Chemistry Topics

Paper 3: Any Topics

Different exam boards have different topics. I hope you have been studying the spec that you will be learning. AS isn't thaaat different between the boards, so it won't have hurt much if you did the wrong one.

Not all (not many) schools have their students take AS exams at the end of Y12. Most students just take the three exams at the end of the course, but those exams will include content from both years of the course.
